To all whom it may concern:

Be it known that I, ALPHONs H. Grrs, a

citizen of the United States, residing at Chicago, in the county of (look, State of Illinois, haveinvented certain new and useful Iniprovements in Drive-Belts; and I, do hereby declare the following to be a full, clear, and exact description of the'invention, such as will enable others skilled in the art to which it appertains to make and use the same. This invention relates to belts and more particularly to that class which are made up of metallic chain and leather or'other frictional material.

In providing a belt constructed as will be presently fully described, I have in view the production of a belt which vill-not stretch, will be strong and durable, flexible, and in which the friction-element or material will have a firm backing. T his last mentioned advantage 1 secure by using a chain which is beveled in cross section and the side por tions of the friction material rest against the beveled sides of-the chain and are firmly braced thereby'providing for a greater friction surface.

In the accompanying drawings, Figure 1 is a side elevation of a length of the belt. Fig. 2 is a top plan View thereof, Fig. 3 is a bottom plan view, Fig. 4 is a vertical longitudinal sectional view through the length,-

and, Fig. 5 is a similar view taken transversely of the belt in a line with one of the bolts for securing the friction material to the chain. i I

In the accompanying drawings, the belt is shown as being composed, inpart, of a chain which is of substantially the same construction as' an ordinary'bicycle sprocket chainand which is rnade' up of blocks'fi and links 7,

' the latter having their outer faces beveled as indicated by the numeral 8.

The friction element of the chain is in the form of a strip 0 of raw-hide or other suitable material having frictional properties and this strip is secured to the under side of the chain by means of bolts 10 which have rather large,

' but fiat, heads and have engaged upon them nuts 11 and washers 12, the said washers be;

ing interposed between the nuts and the fric tion strip. These bolts are passed between the links of the chain and through rectanguposed and held by the bolts, against the upper surface of the chain. The raw hide is so shaped transversely that it not only rests against the beveled sides of the links thereof be readily understood as a solid backing for the str 1 I r raw hl e. terminate directly beneath-the the upper surface of thejchain' and conse quently the chain is prac tically inclosed. throughout its entire length and is therefore protected from the elements.

We dging of the chain'in the .grooye'of the pulley around which it is passed.-

vention, it will be seen that a belt of this class which is inelastic, durable, strong, and above all very flexible, and furlinks of the chain, a maximum face'is provided for.

What is claimed is:-' v 1'. A drive belt of the class described com- )locks and links, afriction strip disposedbolts dpassed through each of the last mantione v pair of links of the chain.
